Aerial stem-parasitic shrubs, mostly glabrous, robust, with epicortical runners bear-ing secondary haustoria. Leaves alternate, opposite or verticillate. Inflorescence a robust many- flowered raceme or spike; axis with a non-flowerbearing part at the base or apex; bract single under each flower, simple. Fruit ellipsoid to obovoid.
Asia-Tropical:, Borneo present; Malaya (Peninsular Malaysia present)
Endemic to Malesia; 5 species in Peninsular Malaysia and Borneo.
Remarkable are the long robust corollas, and in some species the coloured non-flowerbearing part of the inflorescence axis, which may be either distal or proximal to the flowers, and may provide a perch for pollinators (H. Nagamasu, personal communication).
